You can have the LED indicators blink to let you know you have a message waiting.

You can have the telco app wake up the phone and present you with the name of the caller, I programmed the Home Key to answer the phone so no unlocking required to do that.

I don't want email to do anything, so have that turned off. I did look at MyMail notification settings, it can do a lot, but I have all notifications turned off on my phone so it can't do anything anyway.

I see that NiLS Floating Panel was suggested while I was writing this post.... that looks like a good option to try. However, I did see where someone says it doesn't work with the S5.... please come back and tell us your results with trying on your S5.
